Question

Write the all formulas of Introduction to trignometry....... No spam. Class 10 Mathematics Chapter: 8​

Answer 1

Answer:

Hii Malayali....

Your answer is here..☺

First I would tell you about basic formulas like,

$\mathfrak{ Formulas \: of \: Trigonometry }$

1       sin A Perpendicular/Hypotenuse

2 cos A Base/Hypotenuse

3 tan A Perpendicular/Base

4 cot A Base/Perpendicular

5     cosec A Hypotenuse/Perpendicular

6 sec A Hypotenuse/Base

OR,

$sin \: A = \frac{1}{cosec A}$

$\: cos A = \frac {1}{sec A }$

$\:tan A =\frac{1}{cot A }$

Trigonometric Identities:

sin²A + cos²A = 1

tan²A + 1 = sec²A

cot²A + 1 = cosec²A

Hope this answer can helps you dear...☺

All the best for your studies too..♥

Answer 2

ITHAAA MOTHOOOSEEE  ANSWER.....

sine of angle θ = sinθ ⁡ = PerpendicularHypotenuse.

cosine of angle θ = cosθ ⁡ = BaseHypotenuse.

tangent of angle θ = tanθ ⁡ = PerpendicularBase.

cotangent of angle θ = cotθ ⁡ = BasePerpendicular.

cosecant of angle θ = cosecθ c o s e c θ = HypotenusePerpendicular.
